Mobility in developing world cities is a very peculiar challenge, because different from health or education or housing, it tends to get worse as societies become richer. Clearly, an unsustainable model. [16] Mobility. as most other developing country problems, more than a matter of money or technology, is a matter of equality. The great inequality in developing countries makes it difficult to see, for example, that in terms of transport, an advanced city is not one where even the poor use cars, but rather one where even the rich use public transport. There is a conflict for space between those with cars and those without them.
    We fought not just for space for buses, but we fought for space for people, and that was even more difficult. Cities are human habitats, and we humans are pedestrians. Just as fish need to swim or birds need to fly or deer need to run, we need to walk. [17] I would like to focus on the really enormous conflict between pedestrians and cars in developing country cities. In terms of transport infrastructure, what really makes a difference between advanced and backward cities is not highways or subways but quality sidewalks.
    I will propose to you a couple of ingredients which I think would make cities much better, and it would be very simple to implement them in the new cities which are only being created. Hundreds of kilometers of greenways crisscrossing cities in all directions. People will walk out of homes into safe spaces. They could go for dozens of kilometers safely in wonderful greenways, sort of bicycle highways.
    And the second Ingredient, which would solve mobility, that very difficult challenge in developing countries, in a very low-cost and simple way, [18] would be to have hundreds of kilometers of streets only for buses, bicycles and pedestrians. This would be, again, a very low-cost solution if implemented from the start, low cost, pleasant transit with natural sunlight
    But unfortunately, reality is not as good as my dreams. All developing country cities have a large problem of slums, which means illegal housing. And of course it’s very difficult to have mass transit or to use bicycles in such environments. But even legal housing developments have also been located in the wrong places, very far from the city centers where it’s impossible to provide low-cost, high-frequency public transport As a Latin American, [19] I would recommend, respectfully, passionately, to Asian and African countries which are yet to urbanize, that governments should acquire all land around cities. In this way, their cities could grow in the right places with the right spaces, with the parks, with the greenways, with the busways.
    16. What do we learn about the problem of mobility in developing countries?
    17. What is the focus of this speech?
    18. What is the low-cost solution for mobility challenge in developing countries?
    19. What is the speaker’s suggestion to Asian and African countries yet to urbanize?

选项 A、Use of bicycle among a large population.
B、Development of transport infrastructure.
C、Greenways crossing a city in all directions.
D、Streets for public transport and walkers only.

答案D

解析 据主讲人所说,解决流动性问题的低成本且简单的方案(low-cost and simple way)是在城市建造数百公里的公交、自行车及行人专用道,D项中的public transport概括了录音中的buses和bicycles,而walkers则与pedestrians对应,故D项是正确答案。A项“大量人口使用自行车”未在讲座中提到。主讲人提到transport infrastructure包括高速公路、地铁和人行道,所以B项“发展交通基础设施”外延过大。C项“纵横交错的绿道”是第一个建议,本题问的low-cost solution与第二个建议有关,故排除C项。
